Question

calcule os valores algébricos de y nas equações:



2x+y=10
-16x+8y=64
8z-24y=0
16d+32y=16y

Answer 1

Oie, Td Bom?!

1.

2x + y = 10

y = 10 - 2x

2.

- 16x + 8y = 64

8y = 64 + 16x

y = 64/8 + 16x/8

y = 8 + 2x

3.

8z - 24y = 0

- 24y = - 8z

y = -8z/-24

y = 8z/24

y = 1z/3

4.

16d + 32y = 16y

32y - 16y = - 16d

16y = - 16d

y = - 16d/16

y = - d
